Ignition trouble

[Darrell]

Hello iv had this sj for a hole now and the old owner had to try and got wire the car to get it going cuz it had the ignition barrel smashed an what he did was bridge the two wires in the plug with a hair pin and touch the black and yellow one to the hair pin is this correct? I'm stuck

Yes

But what are the two wires connected??
A white/yellow one
and a ???? one (shown on the diagram as BYG, but have no idea what colour that is and can't tell in the pic)
